First time liquid helium coolant in CEBAF becomes
superfluid, allowing for stable operation of the electron beam. Helium in CEBAF
remained superfluid until Hurricane Isabel took the Central Helium Liquefier
down in 2001

First beam is delivered to an experimental hall on July 1
(Hall C), marking the beginning of operations of the first large installation
